YAMAHA YZF R1 1998-2001.
-
Replacement polished stainless steel exhaust headerpipes to fit your Yamaha YZF R1 1998-2001 .
-
This is a hybrid of a race system and road exhaust, allows you to ditch the cumbersome Exup valve and servo.
- A common fault on the R1 is corrosion of the Exup valve, resulting in blowing headers (MOT failure) and broken control cables from the valve seizing shut. Causing power loss and/or that annoying rattle from the valve. Our headers do away with the whole Exup housing and troublesome valve. Basically its a set of race headers that allow you to use your standard silencer.
